To all 'who/m it may coneem: i

Be it known that I, VoLnnY W. Mason, a

' citizen ot the United States, and e' resident increased or diminls of Frovidenoe, in the county of Providence and State -o Rhode island, have invented e videiinproved meens'for applying a breke further object is to provide aconvenient arrangement whereby the virtual length of the lever for operatin theA winch may be' :is desired. The invention consists in the construction and combination of parte to be .more fully y described hereinafter' end'definitely set forth inthe claims. I

Reference is to o e had' to'theaoooinpany nig drawings forming a part ot this .speeili cation, 1n which similar characters of reference indicate corresponding perts in all the Figure 1 is en'end elevzition constructed according to representing a portion of of e winch my invention., and a dei-rich to which 4the winch' is attached; Fig. El is a "iront elevation of the "Winch, and showing a portion ot the derriclr; Fig. 3 is e longitudinal central section ou the line 3-3 of Fig. 1, and passing through the drum of the Winch and the bearings therefor; this viewelso shows n' portion of thederriok incross section; Fig. 4 is asection taken'on the line 444 of Fig-l, :indshowing contiguous parts broken evvey; Figo is a vertical section taken at the brakeband lever, and illustrating the manner in which the lever operates to applytlie brake or release the saine; contiguous parts in this AView ere represented as broken away; and Fig. 6 1s a cross section teken on the line of?, of Fig. 5.

RHODE ISLAND' meenemen. ab, 190e.

or space 4f, in which a drum 5 is rotatably mounted., l l Referring especially to? Fig. 3, in order to support the drum, the shaft 6 thereof 1s 10- tatably mounted in suitable bearing-cape Q which oeps are attached by bolts, as indin cated, to the freine 3. Between the been ings,` which are preferably provided with rollers S, is provided si drum 5. This drinn comprises e cylindrical sleeve 10 of enlarged diameter with respect to the shaft 6, and this sleeve is formed integral with an outer head 11.

The main head` i2 of the drum .is prefer ably provided on its inner tace WitlLa boss 13, which sets into the bore lli of the sleeve 1G,` as indicated, end this inain head 'is rigidly secured to the body ot" the drum by means of suitable bolts 15. This main head 12 is, of soin-se, of circuler form, and is provided et its outer extremity with a laterally projecting innge 16. The outer face of this flange is snioetin and is bralzeband applied thereto, 12 constitutes a bralfiefwheel. The inner side of: the flange 16 is formed with teeth 17, so that this head constitutes an internal gear,

so that the heeft as will be readily understood.

Att e. suitable pointin the treme 3. e. stubshe't 18 is provided, thesame being rotate bly mounted in 'e suitable bearing 19; this bearing ispreferably provided with rollers 20, as indicated. lwlie inner extremity of 'the stub-'shaft i8 carries rigidly e 'pinion 21,

which meshes with 'he aforesaid teeth l', enu abling the rotation of the stubshet 18 to be transmitted to the drum; The central. portion of the outer end face of the' stub-shaft 18 is removeda indicated at E22, and et this point the stub-shaft is provided with olining in Fig. 4.. for a liendflever, the body whereof is slidable through the slots, es will'be reeclilyl understood. This hand-lever 24 is provided at its extremity with a handle 25, so that it' constitutes e, crank, enabling the pinion 2l to be rotated nwhen desired. l provide ,un arrangement For enabling the lever 24 to be held in dit'ferei'it adjusted positions. For Athis purpose. the extremity or encl face of the stub-shaft 'lit is providecdiswith an en- Alarged boro 2o, which is concentric Awith e .boie' 2T oi smaller diameter.

.ln the bore a pin 255 is mounted, the 'saine lievlng e adapted to have the Sti 9.5 transverse slots 23, es indicated most clearly -l These slots 23 constitute e guide shackle 3l) is provided head 30 disposed in the large bore 26. Under the heed 30. e. helical 'spr'ing 31 is placed, which thrusts against the bottom of the bore 26, tending to force the pin out :wardly The outer face of the. head. 30 is formed with e conical knob or point 82, end. 'the spring 3l operates to hold this point 'against the inner fece of the lever lllhe inner fece oi the lever is provided'with is plurality of conical recesses 33, which are .adapted to be engaged .by the iin't, es `will be readily understood, so as no ook the .lever against accidentel displeccment. ln operating the crank, however, it should be understood-that when e sniicient force is exerted tending to slide the lever liiangitndinelly, the pin 28 will not operate to prevent lsuch movement; and when "the lever is slid along as suvges'ted, to shorten or lengthen the virtual cvernrin the spring 31 Will operate to force the pin into the next recess 33 esV it passesthe pin. ln this wey, arrangement is made for locking the lever against eccidental displacement, and at the seine time I am enabled to shift the leverso :as to increase orydccrease the leverage,- Whe-n desix-ed. Such an arrangement as this is often desirable, Where changes in the character of the movement must he mede. This movement is also advantageous Where e load is to be allowed to run down; in this instance it is desirable to shorten the erin of the lever 24 so as to reduce the danger from accident in its rostion.

As indicated most clearly in Figs. and :2, -et a suitable point von .the frame '3 is provided a pair of ears 34e, between which is pvoied n. block 35. T his block ineens for attaching e brake-band 36, seid brake-hand being provided with a. bolt 37 :it its extl'emify, which passes through the block, said holt havingI nuts which screw respectively against the Aopposite feces of the block, so :is to secure fhe hrakelnind, :is Will be readily understood. rlhc body ol the brake-hand is curved so as to correspond to lhe curvature of the ilsnge i6, and lies adjacent to the oui-ei' fece. thereof, as indicated most: clearly in Fig. l. The lower ex tremity of the bend rigidly :lttached to '.1 shackle 239, which preferably curves inwardly, :is shown, at its extremity, This with a central slot 40. :is shown most clearly a convenient point the frame 5l is provided With opposnely disposed cnrs 41, between which :L brake-level' 4Q is znonnled on :1 Snit- :ihlc pin 43. This [Hinke-lever isa hcll-crzmk lover, the short arm 44 whereof attaches hv moans ci' :l pin lo the extremity of the shackle b9. vThe long' ern] 4.6 of the brekelcvcr projects downwardly and passes through the slot 40.

Referring to 5, it w Y ill he seen that the 'curvature of the shackle 39, referred affords in lligs and 6. At g sowie above, results in throwing the pin i5 normally on the opposite side of the pin 43, and opposite to the extremity l? of the brakebend which is attached to the shackle. Virhen the parts are in the relation shown in Fig. 5, the brekedoand 36 is not pressed against the face 9i the 'flange 1Q. W hen 1t desired to elpply jthc braille, it is only necessziry to 'pnl the" lever-erin i6 upwnzirdiy into s position such as that shown in Fig. 1. As this movement progresses, the short erm 44 moves downwardly and operates to pull or stretch the brake-band. W'hen the arm arrives at substantially the position shownin Fig. 1, the maximum tension. in the brakelienfi Will exist',4 `When the lever arrives lie-f yond its dead center it enga gesithc extremity or edge of the slot 40 in the end of the shackle. in' this way, the shackle and lever 46 cooperate to maintain the tension brought K about in the brake-hand.

In order to facilitate the ettnchlnent of the cable 48 to the drum, I provide inclined 'openings 49 end 50 at the heads 11 and l2.

These openings pass through the outer feces of the heads, and communicate with the bore li of the drum body. .-.fit the same time they are formed so iis to intersect the .angle between the heads and the body of the drinn, and in `this wey openings 5l and 52am formed, `Which lead from the outer faces of the drum body to the interior thereof. This :ii-rangement oi openings highly advantageous, :is it enables the cable to he ,brought out to the fece of the bodyl of the either extremity'othereoi, and also enables the attached end of the czihle to be secured to either heed of the drum. i prefer to atnch the fixed end of the cable to the inner i'uce of the heed 12 by Ineens of a suitable clip or plato 53, as indicated in Fig. 3. v In order to facilitate the placing of the cable in positioin the body or sleeve 1),of thc drum is preferably provided near its iniddle point with .fi longitudinally disposed slot :il which facilitates the insertion of an instrument such ns a spike, which will enable he calde to he advanced along the shaft. 'Xccdlcss to say, this slot 54 is placed in lon'- gii'ndinnl nlinenxent between the openings 49 :ind 50. Having thus described my invention, l claim :is new :1nd desire to secure by Letters Patent: l. ln :L winch, in combination, e frame, a lover mounted on said frame, a drum,.a lvmkewheel rotating `Wiih said drum, a ln'nlio -lmnd cooperating with said brakewheol, n shackle attached to the extremity of seid brnkehand ver, said lever allordingmeansior tightening;A said brake-band on said Wheel, and means whereby seid lever may engage scid .shackle to limit the movement thereof and to l lock said hand.
